variants with their own articles=The Valmet Tuuli was a trainer aircraft, developed for the
Finnish Air Forceby the State Aircraft Factory("Valtion lentokonetehdas", VL). The aircraft was to be produced in 3 different versions. The last version, Tuuli III was redesigned from scratch, and is basically an entirely different aircraft.
The design work on the aircraft was initiated in February 1941 under the leadership of the chief engineer Martti Vainio. The aircraft was a low-winged, tandem-seated trainer aircraft. The Finnish Air Force ordered a prototype, Tuuli I, in August 1942. The design work and its construction was ended in the spring of 1944, when the aircraft manufacturer was forced to put all its efforts in repairing the front-line aircraft. The Tuuli I was never finished.
In 1944 VL became part of the company "Valtion metallitehtaita" (
Valmet) and therefore, this prototype became Valmet's first aircraft. Valmet wanted to transform weapons factories, which were currently focused on war-reparations to the Soviet Union, into a productive and profitable industry. Artillery factories were transformed into paper machine factories, etc. The leaders of the aircraft factory became professors of the Helsinki Technical University and directors of VTT. At this stage, the design of aircraft in Finland was cooled down and the quality suffered.
The design of the Tuuli II prototype began in September 1945 and was led by
Torolf Eklund. The prototype was ready in the autumn of 1948. After this, the development stopped for a couple of years. The air force funded the prototype, and promised an order if it filled their requirements. The requirements had changed, and now the aircraft had to have side-by-side seating. The maiden flight with the Tuuli II was on September 26 1951. Due to its low wing loading, its turning maneuvers was bad - this was from the military's view a serious deficiency. The aircraft was destroyed on October 26 1951. The accident happened after the control stickhad broken off, due to a forgotten stage of rivetting.
A third prototype, the Tuuli III was designed in 1957-59, after the FAF had announced the requirement of a new trainer aircraft. However, the Tuuli III lost the competition to the Swedish
Saab 91 Safir, which was much cheaper. The Tuuli III was to be the last military aircraft designed in Finland until the Valmet L-70 Vinkain the 1970s.
